Acknowledge implies making a statement reluctantly, often about something previously denied: to acknowledge a fault. Admit especially implies acknowledging something under pressure: to admit a charge. Confess usually means stating somewhat formally an admission of wrongdoing, crime, or shortcoming: to confess guilt; to confess an inability to understand.


1. deny, disclaim, disavow.

Word Origin & History

acknowledge
1550s, a blend of M.E. aknow (from O.E. oncnawan "understand," from on + cnawan "recognize;" see know) and M.E. verb knowlechen "admit." Somehow, in the merger, a parasitic -c- slipped in, so that, while the kn- became a simple "n" sound (as in know), the -c- stepped up to
preserve, in this word, the ancient "kn-" sound.
